[0001] The utility model relates to a bottom grid fence with adjustable fence gap, which is applied to a bottom grid fence dam adopted in a mountain river and belongs to the technical field of bottom grid fence flow-through. Background Art

[0002] Bottom grid fence dam is usually suitable for mountain rivers with a large amount of sand and gravel in the water flow. Part or all of the water in the river flows into the water diversion corridor through the gaps in the grid. The bottom grid fence blocks a large amount of sand and gravel larger than the gaps in the grid from entering the water diversion corridor, and then flows into the downstream with the water flow.

[0003] Mountain rivers have dry seasons and flood seasons. In the dry season, the water flow is small, and the amount of sand and gravel carried by the water flow is also small. In the flood season, the water flow is large and the water flow is fast, and the water flow carries a large amount of sand and gravel. The gap between the fences affects the drainage capacity of the bottom grid fence. The gap between the traditional bottom grid fences is designed and determined according to the annual sediment transport volume of the local river. The fixed gap between the fences has limited effect on improving the drainage capacity of the bottom grid fence, and the river water flow cannot be effectively utilized.

[0004] Therefore, it is necessary to study a bottom grid fence with adjustable fence gap to effectively utilize river water and improve the drainage capacity of the bottom grid fence. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model will be further described in detail below in conjunction with the accompanying drawings.

[0023] Example

[0024] like Figure 1-2 As shown, a bottom grid fence with adjustable fence gap includes a plurality of fence bars 2 located above a water diversion corridor 3 and arranged along the water flow direction, and fence gap adjustment devices 1 are provided at both ends of each fence bar 2 for adjusting the gap between the fence bars 2. When the bottom grid fence is applied to a bottom grid fence dam used in a mountain river, the bottom grid fence structure is installed on the bottom grid fence dam body, and the bottom grid fence dam includes a bottom grid fence dam base 4, one side of which is the water-facing surface, and the other side is the water-receiving surface, and a water diversion corridor 3 is formed in the middle, and the water diversion corridor 3 is connected to the sand settling tank in the bottom grid fence dam, wherein the fence gap adjustment devices 1 at both ends and the plane structure formed by the fence bars 2 are fixed between the water-facing dam stem surface 5 and the water-receiving dam stem surface 6.

[0025] like Figure 3-6 As shown, the fence gap adjustment device 1 includes an adjustment device 11 and a sliding device 12; the adjustment device 11 includes a bar head 113 arranged at the end of the fence bar 2, and a first bolt 111 vertically penetrates the bar head 113, the upper end of the first bolt 111 is connected to the adjustment ring buckle 112, and the lower end is connected to the sliding device 12; the sliding device 12 includes a matching pulley 121 and a slide rail 124, the pulley 121 is connected to the first bolt 111 through a pulley support, and the slide rail 124 is arranged on the dam body along the vertical direction of the fence bar 2.

[0026] Among them, a number of through holes are opened on the adjustment ring buckle 112. When the gap between the fence bars 2 needs to be adjusted, the pulley 121 is slid according to the demand, thereby driving the fence bars 2 to move. When the spacing between adjacent fence bars 2 reaches the ideal state, the through holes in the corresponding positions are selected to cooperate with the first bolt 111 to fix the fence bars 2, thereby realizing the adjustment of the gap between adjacent fence bars 2.
